B.IntroductionThank you for purchasing this 2.4GHz Digital AV Sender. This sender system is a digital wireless audio/video sender that uses 2.4GHz Frequency Hopping technology and GFSK modulation, and random ID codes to protect personal privacy.There are over billion hopping sequences to minimize interference and deliver consistently an excellent video and audio quality up to 150 meters away.Using this 2.4GHz Digital Wireless A/V Sender, you can enjoy greater convenience and security in many ways:Safety & Security Application: ▪ Connect a camera as a wireless security system. ▪ Monitor your sleeping baby, playing children, the elderly, or the disabled on TV using your existing camcorder. ▪ See who is outside the door on TV through your camera or miniature CCD camera. ▪ Monitors and records the meeting from another room. ▪ And many more uses!C.Product LayoutPairing ButtonsPower LEDDC Jack for adaptorAV Jack for Output(TX) or Input(RX)Pairing ButtonsPower LEDDC Jack for adaptorAV Jack for Output(TX) or Input(RX)-3-F.Use NoticsG.Troubleshooting1.Be sure the transmitter and the receiver were connected to the equipment correctly (e.g. Connect the transmitter to the camera, and the receiver to the TV or DVR).2.When DC plug is pulled out from transmitter or receiver, it needs to wait for a few seconds to insert it again.3.Adjust antenna to decrease interference. (vertical or horizontal)4.In most situations, one pair has a better distance up to 150 meter(open site). When two pairs or more are used at the same time, It can automatically jump to different channels. But the distance between transmitter and transmitter (receiver and receiver), preferably greater than 1.5 meter far.5.If there are some reasons cause the devise stop, you can try to turn power switch off then on again and make the devise re-link.6.It is suggested to have 10 pairs mostly operated in same location.Possible SolutionCheck all cable connectionsMake sure power plugs are pushed all the way inCheck power switches on the remote TV or DVR and Video source(Camera, Camcorder, etc.)Check if the POWER LED of the transmitter and receiver is lighting or not? Their LINK LED should be lit.If Their LINK LED should not be lit, you must re-pair their codes following the D. instruction of the manual Adjust receiver and transmitter antenna orientationTry to place transmitter and receiver in a more close-in locationIf using a microwave oven, turn it off.Remove microwave oven or wireless router from path between transmitter and receiverProblemsNo picture or soundInterference: picture or audio-6-

If wants to re-pair them, you have to follow the instructions as below:1.Power on the transmitter and receiver by inserting the power adaptor jack.2.Press the pair button of transmitter or receiver and not release until the power LED begin to flash, then release the pair button.3.They will enter into the pairing state and automatically link to each other by ID code after step 2 finished.4.Please don't turn off their power switch during the paring status.5.When pairing successfully, the power LED for both will be lit directly (not flash)Please note:Pressing the pairing buttons for transmitter and receiver is not necessary at the same time, and they are not necessarily put near or side by side in pairing status, around within 3 meters far is OKUnder the transmission, you can see the strength on the monitor as below:-5-
